Does it work as kernel parameter?
I tried libata_dma_mask=0x4 and to set 0xf or 0xff - doesn't help. How to
disable DMA in libata, if it is compiled in kernel?
libata.dma_mask=3
will leave you with CD and disk

It's libata.dma if its built into the kernel, or 'dma' module option
if built as a kernel module.

Seems in libata there is no fall-back to non-DMA mode, if DMA didn't work.
It should be falling back from UDMA or MWDMA to PIO, if not please file a
bug

There is, it's just too conservative about that. With improvements
pending for 2.6.24, it should be quite snappy at falling back to PIO if
configured transfer

This is another flash (1GB probably original Sandisk), 16MB one is called
SHARP, and it is 2-4 years old. Maybe it is some noname with incorrect
identification data. But it works well in USB card reader.

CFA spec requires 848a in word[0], not 844a, which explains
why hdparm thought it might be ATAPI. I've updated my hdparm
source to detect this for hdparm-7.8 (unreleased).
That card (16MB) is definitely buggy.
But your other (1GB) card looks fine.
Thanks. Somebody else may help with the

I am using Gentoo (and it is custom build of linux, actually only busybox +
kernel + uclibc and few other tools), hdparm is vanilla 7.7
I will try to compile now -rc2 to see if there any changes.
With 16MB 2.6.24-rc1 works fine, 1GB working also with some errors in dmesg.
And IF that all is
You are right, seems no dma lines in adapter. hda=nodma helped, no errors
anymore. I will try now also libata_dma_mask and will mail result. Btw there
is no notes in Documentation/kernel-parameters.txt about it.
In any case it is complete board, WRAP.2C made by PCEngines in 2003. Kind of
